The Buddha's Awakening gave him, among other things, a new perspective on the uses and limitations of words. He had discovered a reality — the Deathless — that no words could describe. At the same time, he discovered that the path to Awakening could be described, although it involved a new way of seeing and conceptualizing the problem of suffering and stress. Because ordinary concepts were often poor tools for teaching the path, he had to invent new concepts and to stretch pre-existing words to encompass those concepts so that others could taste Awakening themselves.
